Are you talking about PM,
Jack? If so, it's no dilemma. PM (which includes "safety inspections") should be carried out (by tradition) at least once a year. Myself, I always prefer to aim at every 180 days (that is, every six-months) for electro-medical equipment such as this.
Never mind what the users manual says ... it's the condition of the equipment that matters. What does the
technical manual have to say, by the way? And how come you're not doing the "inspections" yourself, I wonder?
BTL ... not Baird & Tatlock then!
